- INTRODUCTION TO ENDOCRINE SYSTEM
This lecture covers endocrine development, note that a better understanding can be made if you understand the adult function of each endocrine organ (though this will not be covered in the Lecture). Endocrine development is sometimes divided into neuroendocrine and endocrine and is also generally covered piecemeal in all embryology
Objectives: To study the nature, types, general mechanism of action of hormones. To learn about the chemistry, synthesis, metabolic role of various hormones. Contents. Introduction. Synthesis and release of hormones. Functions of hormones. Classification of hormones. Mechanisms of hormones action. Regulation of hormone levels. Hormone inactivation.
1 The Endocrine System By Arnav, Kevin and Keira 2 What is the Endocrine System? The endocrine system regulates metabolism, tissue function, growth and development, reproduction, sleep, and...
There are two types of hormones secreted in the endocrine system: Steroidal and non-steroidal, (or protein based) hormones. The endocrine system regulates its hormones through negative feedback, except in very specific cases like childbirth.
10 sie 2019 · The endocrine system is made up of glands that produce and secrete hormones which regulate growth, metabolism, sexual development and homeostasis. The major glands include the hypothalamus, pituitary, thyroid, parathyroid, adrenal, thymus, pineal, reproductive organs and pancreas.
Secretion of hormones is regulated by: 1. Ca2+-dependent exocytosisexocytosis (pituitary hormones, insulin, adrenaline) Ca2+ Synthesis - storage in vesicles - vesicle fusion with the membrane – hormone release. 2. By cleavage of the storage molecules (thyroid hormones – from thyroglobulin). 3. Adrenal steroids: little stor age but massive ...
